There was some question as to installing software to access google drive earlier (didn't seem desirable, needed). Shared access to a website wouldn't need that extra software. It is, however, probably not required. ECF has its own backup procedures, I would guess.

I have absolutely no problem with you using cloud based stuff for your own personal use. Nor for having a virtual spreadsheet app and storage in the cloud for sorting your stuff. I don't even care if 1 person was using virtual everything... since it's hard to differentiate between cloud drive+apps and local hard drive + local software on someone's computer in that case.
Now we're getting into shared stuff, and information sharing. The list itself doesn't contain much information (username, date-time for party, theme, thread-starter) and all of it I could get just reading public threads even without an account on ECF. However, I would rather keep it close to home and on ECF if you gave me a choice between the two options.
This is just my personal opinion and
I think the main advantages of google docs, or other solutions are concurrency control, versioning and in some cases simultaneous editing (a form of concurancy control... of sorts).
I want to see what our options are for list posting in PVT and posting hot links to it using j0ker's solution.
EDIT: Also note that if you decide to delete "your" website for any reason, we'd be back to square 1. Not say'n that you would........
